Filed: 1926-06-21
Abstract: 253,941. Miller Train Control Corporation, (Assignees of Rice, P. X.). June 10, 1925, [Convention date]. Fluid-pressure.-According to the Specification as open to inspection under Sect. 91 (3) (a), the ordinary driver's valve is opened by a chain connected to a piston in a cylinder which is vented to atmosphere when a valve normally held closed by the armature of an electromagnet is released by co-operation of iron plates on the tracks with train-carried magnetic cores, which are in some cases fitted with short-circuited coils to vary the flux in the cores on the train. Alternatively the valve may be controlled by a pivoted armature in the magnetic field of the cores on the train. Fig. 2 (Cancelled) shows the driver's valve 5 operated by a flexible chain 17 connected to the piston 12, the upper side of which is subjected to train reservoir pressure through pipe 9. A vent 13 equalizes the pressure on the lower side of the piston which is connected to the vent valve 25. comprising a plunger 30 normally held against its seating by the spring 31 mounted on a pivoted armature 32 which is retained against the poles 33 of an electromagnet energized by an alternator generator carried on the train. The magnets and armature are secured to the valve casing by screw-clamps 36, which permit suitable adjustments. This subject-matter does not appear in the Specification as accepted.

IPC: H01H33/70
Filed: 1952-06-20
Abstract: 720,331. Gas-blast switches. ALLISCHALMERS MANUFACTURING CO. June 20, 1952, No. 15578/52. Class 38 (5) A gas-blast switch has an arc chute with two blast passages 15, 16 and a blast divider 19 extending from a point upstream of the switch contacts 7, 8 to direct a high intensity stream of gas into the passage 15 to interrupt relatively high currents and a lower intensity stream of gas into the passage 16 to interrupt relatively low currents. The blast divider 19 provides a pair of nozzles 22, 23 which diverge from the inlet end of the divider, the nozzle 22 being substantially coaxial with the supply conduit 13 and the passage 15 so that the major part of the blast flows through it. The nozzles 22, 23 are substantially closed by the moving contact blade 8 when in the position shown. The blast passages 15, 16 contain electrodes 25, 26, the electrode 25 being connected to the fixed contact 7 through a current-limiting resistor 27. When the contacts are opened, the initial movement of the contact 8 draws an arc and uncovers the nozzle 22, the blast through the nozzle 22 blowing the arc into the passage 15 where it comes into contact with the electrode 25. A portion of the arc is now shunted by the resistor 27 and extinguished. The portion of the arc in series with the resistor may be extended into the passage 16 as the contact separation increases and there extinguished by the lower intensity stream of gas which flows through the passage 16 when the contact 8 uncovers the nozzle 23.
